The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1] Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its vicinity.
The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania to southeastern New York. Map of the Ramapo Fault System: Earthquake epicenter at Lebanon, NJ.
The causative fault for the earthquake was likely in the area of the Ramapo Fault zone, which extends from Pennsylvania to New York and was formed by the break-up of the supercontinent Pangaea during the Late Triassic. Another possible origin is the Flemington Fault, a younger fault in the same area.
The Ramapo Fault, which marks the western boundary of the Newark rift basin, has been argued to be a major seismically active feature of this region, but it is difficult to discern the extent to which the Ramapo fault (or any other specific mapped fault in the area) might be any more of a source of future earthquakes than any other parts of the ...
In New Jersey, fault lines do not generally break the Earth's surface, but are based several miles below. A map showing the physiographic provinces in New Jersey, and the location of the Ramapo Fault.
April 5, 2024 at 7:37 PM. The fault that ruptured beneath New Jersey on Friday morning was likely an ancient, sleeping seam in the Earth, awakened by geologic forces in a region where earthquakes ...
The Ramapo Mountains are a forested chain of the Appalachian Mountains in northeastern New Jersey and southeastern New York, in the United States. They range in height from 900 to 1,200 feet (270 to 370 m) in New Jersey, and 900 to 1,400 feet (270 to 430 m) in New York. Several parks and forest preserves encompass parts of the Ramapos (see ...
And its major fault system, the Ramapo Fault, was created quite differently. North America, Europe and Africa were once part of a single giant tectonic plate, called Pangea.
